0.025 ml. of turpentine-oil was injected into rabbit ear and the effects of acupuncture on the inflammatory reaction were observed. Acupuncture was performed 0, 3, 6, 24 and 48 hrs. after the injection. The points acupunctured were Hegu, Zusanli, Quchi and Yifeng. Each time the needling of a point lasted 1 min. with the needle thrusted, lifted and twisted twice per second and then remained in situ for 20 min.
The hyperemia, exudation and PMN infiltrations were significantly suppressed in acupunctured animals. The ear-volume of controls steadily increased following oil injection, reached its maximum at the 24th hour (121.8%) and then declined. While in the acupunctured animals, the increase markedly lagged behind, with a maximum increment of 41.8% only. Experiments indicated that intact sympathetic innervation of the ear was necessary for the above effects.
In experiments on rats with granuloma pouch, electro-acupuncture demonstrated similar effects. The volume of exudate and the wet weight of pouch were significantly less in the acupunctured than in controls.
In another group of experiments with rabbit ear, 0.2 microcurie of {32}P was injected into the inflammatory site (outer zone). The absorption rate of the isotope at the 29th min. was 63.7% in the acupunctured versus 25.6% in controls. This suggested an improvement of local circulation and lymphatic drainage, and the latter was also confirmed by lymphographic studies.
